                                        2
<PAGE>
                  Aircrew Training Devices. The Company's aircrew training
                  devices are used for medical research, advanced tactical and
                  physiological flight training, and for the indoctrination and
                  testing of military and commercial pilots. The major devices
                  sold in this product area are military and commercial flight
                  simulators, night vision trainers, water survival training
                  equipment, disorientation training equipment, human
                  centrifuges, ejection seat trainers and vehicle and tank
                  simulators. The Company provides operation and maintenance
                  services for installed equipment it manufactures as well as
                  equipment produced by others.

                  Entertainment Products. The Company's entertainment products
                  consist of motion-based simulation rides and other products.

                  Disaster Management Simulation. The Company's Disaster
                  Management Systems line includes real-time interactive
                  training programs that allow instruction on various disaster
                  situations.

The aircrew training system class of products as a whole represented 69%, 73%
and 76% of consolidated revenues of the Company for the years ended February 22,
2002, February 23, 2001 and February 25, 2000, respectively.

         Industrial Group. This segment includes three primary product lines:
sterilizers, environmental systems and other products, and hyperbarics.

                  Sterilizers. The Company manufactures steam and gas
                  sterilizers for various industrial and pharmaceutical
                  applications. The Company concentrates on marketing the larger
                  custom-designed sterilizers to the pharmaceutical and medical
                  device industries.

                  Environmental Systems and Other Products. The Company's
                  environmental systems business consists of the design and
                  fabrication of sampling and analysis systems, and test
                  equipment and systems. The simulation systems generally
                  consist of an enclosed chamber with instrumentation and
                  equipment which enable the customer to control and modify such
                  environmental factors as temperature, pressure, humidity, wind
                  velocity and gas content to produce desired conditions. These
                  products include controlled air systems for automotive
                  companies and environmental chambers for HVAC and other
                  applications.

                  Hyperbarics. The Company's Hyperbarics line includes monoplace
                  (single person) and multiplace (multiple persons) chambers for
                  high altitude training, decompression and wound care
                  applications.


Sales of Industrial Group products were 31%, 27% and 24% of consolidated
revenues of the Company for the years ended February 22, 2002, February 23, 2001
and February 25, 2000, respectively.

The Company also provides control upgrades, maintenance and repair services and
spare parts for its own and other manufacturers' equipment.

For a more complete description of financial information regarding our business
segments, see "Note 10. Business Segment Information" to the Company's
consolidated financial statements incorporated herein by reference to the Annual
Report.

Marketing

The Company currently markets its products and services primarily through its
sales offices and employees. At February 22, 2002, approximately 18 employees
were committed to sales and marketing functions. The Company uses branch offices
in the United Kingdom, the Middle East, and Asia as well as the services of
approximately 100 independent sales organizations in seeking foreign orders for
its products.

Product Development

New products and improvements in existing products are being continually
developed in response to inquiries from customers and to management's
determination that particular products should be produced or significantly
improved. Although the Company does not have a separate research and development
group, there are several technical personnel whose main activity is the
development and integration of new technologies into our existing products.
These personnel include the Vice-President of Engineering and the Vice-President
of New Product Development whose additional activity is the introduction of
product extensions and new applications of existing technology.

Within the Aircrew Training Systems Segment, product development emphasizes
enhancing control systems and software graphics and exploring commercial
possibilities. The Company's product development efforts will be focused on two
areas:



                                        3
<PAGE>

      -  Disaster Management Simulation. The Company is in production of a major
         contract from the City of Chicago to develop, install and maintain a
         computer-based Incident Command Simulator. Additionally, the Company is
         completing orders from respected fire schools throughout the world for
         simulation products. The company will continue to explore product
         applications and extensions to this Intelligent Virtual Reality
         product.

      -  G-force and Disorientation Trainers.
         -----------------------------------

         -    The Company recently introduced a new second generation General
              Aviation Trainer (GAT II). Aimed at the commercial aviation
              market, the GAT II simulates the cockpit controls, displays and
              flight characteristics of general aviation private aircraft,
              business aircraft and helicopters.

         -    The Company has begun testing on its high-end rapid onset
              Sustained G Tactical Flight Simulator, the G-FET II TFS.

         -    The Company recently completed a successful factory acceptance of
              its new GYROLAB(R) GL-1500 Advanced Flight Simulator Spatial
              disorientation trainer.

         -    The Company plans to incorporate additional advanced tactical
              flight simulation (TFS) applications into additional products in
              the ATS line.

         The Company's wholly owned subsidiary, Entertainment Technology
Corporation, develops and manages all of the Company's future entertainment
projects. Product development in this class will emphasize entertainment
applications of our proven ATS simulation technology.

         The Company reported research and development expenses of $600,000,
$903,000 and $920,000 for the years ended February 22, 2002, February 23, 2001
and February 25, 2000, respectively. However, most of the cost of the Company's
research efforts, which were and continue to be a significant cost of its
business, are included in cost of sales for applied research for specific
contracts, as well as research for feasibility and technology updates.

Supplies

The components being used in the assembly of systems and the parts used to
manufacture the Company's products are purchased from equipment manufacturers,
electronics supply firms and others. To date, the Company has had no difficulty
in obtaining supplies. Further, all raw materials, parts, components, and other
supplies used by the Company in the manufacture of its products can be obtained
at competitive prices from alternate sources should existing sources of supply
become unavailable.

Patents and Trademarks

Other than a patent on the GYROLAB Spatial Disorientation Trainer, which expires
in December 2004, the Company has no patents or trademarks which it considers
significant to its operations.

Customers

In the current year and throughout most of its history, the Company has made a
substantial portion of sales to a small number of customers that vary within any
given year. The Company's business does not depend upon repeat orders from these
same customers. Sales of aircrew training systems are made principally to U.S.
and foreign governmental agencies. Sales of sterilizers and environmental
systems are made to commercial and governmental entities worldwide.

In fiscal 2002, the Company's major customers included the Royal Thai Air Force
generating revenues of $3,285,000 and the Walt Disney companies generating
revenues of $15,859,000 or 48.8% and 10.1%, respectively, of total net sales.
These companies do not have any relationship with the Company other than as
customers. The Company expects to continue to conduct business with each of
these companies in fiscal 2003.

Foreign and Domestic Operations and Export Sales

During the years ended February 22, 2002, February 23, 2001 and February 25,
2000, approximately $1,194,000 (4%), $2,063,000 (7%) and $1,587,000 (5%),
respectively, of the Company's net revenues were attributable to contracts with
agencies of the U.S. Government or with other customers who had prime contracts
with agencies of the U.S. government.




                                        4
<PAGE>

During the years ended February 22, 2002, February 23, 2001 and February 25,
2000, $10,110,000 (31%), $15,258,000 (47%) and $23,907,000 (69%), respectively,
of the Company's net revenues were attributable to export sales or sales for
export. (See Note 10 to the Company's consolidated financial statements
incorporated herein by reference to the Annual Report.) On export sales,
customers' obligations to the Company are normally secured by irrevocable
letters of credit based on the creditworthiness of the customer.

The Company does not believe that the distribution of its sales between foreign
and domestic sales for any particular period is necessarily indicative of the
distribution expected for any other period.

A large portion of the Company's sales is derived from long-term contracts
requiring more than one year to complete. The Company accounts for sales under
long-term contracts on the percentage of completion basis. See Note 1 to
consolidated financial statements incorporated herein by reference to the Annual
Report.

The Company's U.S. Government contracts contain standard terms permitting
termination for the convenience of the Government. In the event of termination
of such contracts, the Company is entitled to receive reimbursement on the basis
of work completed (cost incurred plus a reasonable profit), recording the
amounts anticipated to be recovered from termination claims in income as soon as
those amounts can be reasonably determined rather than at the time of final
settlement. All costs applicable to a termination claim are charged as an
offsetting expense concurrently with the recognition of income from the claim.

Backlog

The Company's sales backlog at February 22, 2002 and February 23, 2001, for work
to be performed and revenue to be recognized under written agreements after such
dates, was $28,148,000 and $40,439,000, respectively. In addition, the Company's
training, maintenance and upgrade contracts backlog at February 22, 2002 and
February 23, 2001, for work to be performed and revenue to be recognized after
that date under written agreements was $1,485,000 and $1,347,000, respectively.
Of the February 22, 2002 backlog, approximately $20,967,000 is under contracts
for aircrew training systems and maintenance support including $13,069,000 for
the Walt Disney companies. Approximately 94% of the February 22, 2002, backlog
is expected to be completed prior to February 28, 2003.

Competition

The Company's business strategy in recent years has been to seek niche markets
in which there are not numerous competitors. However, in some areas of its
business the Company competes with well-established firms, some of which have
substantially greater financial and personnel resources than the Company.

Some competitor firms have technical expertise and production capabilities in
one or more of the areas involved in the design and production of physiological
flight training equipment, environmental systems, and other specially designed
products, and compete with the Company for this business. The competition for
any particular project generally is determined by the technological requirements
of the project, with consideration also being given to a bidder's reliability,
product performance, past performance, and price.

The Company faces particularly intense competition from a number of firms in the
sale of hospital sterilizers but faces less competition in the sale of the
larger custom-designed industrial sterilizers.

The Company believes that it is a significant participant in the markets in
which it competes, especially in aircrew training systems in which the Company
believes it is a principal provider of this type of equipment and training in
its market area.

Compliance with Environmental Laws

The Company has not incurred during fiscal 2002, nor does it anticipate
incurring during fiscal 2003, any material capital expenditures to maintain
compliance with Federal, state and local statutes, rules and regulations
concerning the discharge of materials into the environment, nor does the Company
anticipate that compliance with these provisions will have a material adverse
effect on its earnings or competitive position.

Employees

On February 22, 2002, the Company had 276 full-time employees, of whom 6 were
employed in executive positions, 101 were engineers, engineering designers, or
draftspeople, 59 were administrative (sales, accounting, etc.) and clerical
personnel, and 110 were engaged principally in production and operations.





                                        5
<PAGE>

Item 2. Property

The Company owns its executive offices and principal production facilities
located on a 5-acre site in the County Line Industrial Park, Southampton,
Pennsylvania in an approximately 100,000 square foot steel and masonry building.
Approximately 85,000 square feet are devoted to manufacturing and 15,000 square
feet to office space. The original building was erected in 1969 and additions
were most recently made in 2001. This property serves as collateral for the
Company's revolving credit facility. Additionally, the Company rents office
space at various sales and support locations throughout the world and at ETC-PZL
Aerospace Industries, its Polish subsidiary.

The Company considers its machinery and plant to be in satisfactory operating
condition. Increases in the level of operations beyond that expected in the
current fiscal year might require the Company to obtain additional facilities
and equipment.

Item 3. Legal Proceedings

Certain claims, suits and complaints arising in the ordinary course of business
have been filed or are pending against the Company. In the opinion of
management, all such matters are reserved for or are adequately covered by
insurance or, if not so covered, are without merit or are of such kind, or
involve such amounts as would not have a material adverse effect on the
financial position of the Company if resolved unfavorably.

Item 4. Submission of Matters to a Vote of Security Holders

None.

Compliance With Section 16(a) of the Exchange Act

Section 16(a) of the Securities Exchange Act of 1934 requires the Company's
officers and directors, and persons who own more than ten percent of a
registered class of the Company's equity securities to file reports of ownership
and changes in ownership with the Securities and Exchange Commission ("SEC") and
the American Stock Exchange. Officers, directors and greater than ten percent
shareholders are required by SEC regulation to furnish the Company with copies
of all Section 16(a) Forms they file. The rules of the SEC regarding the filing
of such statement require that "late filings" of such statements be disclosed in
the Company's proxy statement.

Based solely on its review of the copies of such forms received by it, or
written representations from certain reporting persons that no Forms 5 were
required for those persons, the Company believes that, during the fiscal year
ended February 22, 2002, its officers, directors and greater than ten percent
beneficial owners complied with all applicable filing requirements.
